Specification of Letters Patent.

Patented July 16, 1912.

Applicatioufiled February 27, 1909. Serial No. 480,332.

To all whom it may concern:

Be it known that I, JACOB J. Mum, a citizen ofthe United States, and aresident of the city of New York, borough of Brook- 5 lyn, in the countyof Kings and State of New York, have invented a new and ImprovedFountain-Pen, of which the following is a full, clear, and exactdescription.

This invention relates to fountain pens and is of that type known asself fillers."

An object of thisinvcntion is to form a fountain pen which will bequickly and easily filled without the necessity of removing thepen-point. This and further objects will be more fully describedhereinafter and particularly pointed out in the claims.

Reference may be had to the accompanying drawings, in which likereference characters denote corresponding parts in all the views, and inwhich Figure 1 is a vertical cross-section of the device, showing thepen-point in an ink bottle, and the cap in the act of drawing the inkinto the pen; Fig. 2 is a view of the pen, showing the cap over thepen-point, and the end-piece closed on its seat; Fig. 3 is a transversecross-section on the line 33 of Fig. l; and Fig. 4 shows a modified formof float-walve.

Referring more particularly to the separate parts of the device, 1indicates the barrel of the pen, to which is secured at one end, apen-point 2 which may be of any suitable form. In Fig. 1 this pen-pointis shown inserted in a bottle 3,from which the ink to be used to fillthe pen is drawn. At the opposite end of the pen-point the barrel isleft open and has an internal fastening means, such as the screw-thread4.

l0 Adapted to engage with this screw-thread is a screw-thread 5 on theend-piece or closing member 6. This end-piece 6' is adapted to screwinto the end of the barrel 1 and close the opening therein. Thisend-piece 6 has a roughened peripheral surface 7 in order that a firmgrip may be obtained to unscrew it. This end-piece 6 is hollow and has avalve 8 which is adapted to slide therein. This valve 8 is fastened tothe end-piece 0 6 by means of a pin 9 which engages a slot 10 on thevalve; thus, a slight sliding motion is permitted between the valve andthe end-piece 6. The valve 8' is adapted to be,

seated on the end-piece as at 11, where the 5 flanges 12 on the valveengage the seat on the end'piece 6. Th s valve 8 may be of any bands ora single suitable form and material; as shown in Fig. 1. it ispreferably of hard rubber. is shown in Fig. 4 it consists of a corkfloat 13 and a suspending wire 11 which has a loop 15 which is adaptedto engage the pin 9 in the same manner in which the slot 10 engages saidpin. The pin 9 is fastened to the end-piece 6 at one end, as at 16, soas to prevent the pin from being jolted out of its position. At theother end the pin 9 passes through a slightly enlarged opening in theend-piece 6. as at 17. This opening 17 permits air to be drawn throughin order to create a vacuum in the upper end of the barrel 1, so that.the ink may be drawn up into said barrel.

The suction necessary to draw up the ink in the barrel is created byforcing the cap 18' over the end of the barrel opposite to that at whichthe pen-point 2 is found. This cap is adapted to be forced down over theend and withdrawn suddenly, creating a vacuum within the cap and thusdrawing air through the opening 17, creating a vacuum within the barrel1, which in turn draws the ink from the bottle 3 up into the barrel.This cap 18 is adapted to engage a slight taper on the barrel 1, as at19, so that the cap will be prevented from going too far on the barrel.This cap 18 also has a slightly weakened section, as at 20. This ispreferably done by removing some of the material of the cap on itsoutside surface. forming an encircling concavity, as at 21. Thisconcavity is adapted to receive a pressing packing 22 which may be ofany suitable form or material, such as a series of rubber rubber band,or an encircling spring. This pressing packing is adapted to create asqueezing pressure on the weakened portion of the cap 18 so that it willbulge internally and will thus form a tight'yielding'fit around .thebarrel 1 during the operation of filling. This packing is adapted to becovered by a band 23 which may be of any suitable material, such assteel or hard rubber. This band 23 protects the packing and holds it inplace.

On the outside of the barrel 1 of the fountain pen are placed at eachend thereof, a pair of grooves 2 1 and 25. The groove 24 takes the placeof the hole which is usually drilled in the cap so that in forcing thecap on the pen the air will not be compressed around the pen-point butwill be permitted. to escape through the groove. In the case of thegroove 25, it is of such length and so placed that it will permit of thecap to be forced over the end opposite to the pen-point withoutcompressing the air under the cap, allowing it tovescape through thegroove. Thus, the air is prevented from forcing the ink out through thepen-point during the first operation of placing the cap on the end.

The end-piece 6 is ordinarily screwed tight onto the barrel, as shOWn inFig. 2. When it is desired to fill the pen, this endpiece 6 is unscrewedjust sufficient to expose the opening 17. The pen is then held in avertical position with'the pen-point at the top. The cap 18 is thenplaced'over the end-piece 6 and forced onto the barrel 1. until it comesin contactwith the tapered surface 19; then the packing 21 forces theweakened portion 20 of the cap in a tight fit around the barrel 1. Thepen-point 2 is then dipped in a bottle of ink, as shown in Fig. 1, andthe cap withdrawn quickly. By this action a vacuum is formed Within thecap 18 and this creates a suction through the opening 17, drawing airbetween the valve 12 and its seat. When the ink in the 'pen reaches thevalve 12, it floats the same up to its closed position. If sufficientink has not been sucked in by one operation, as described, the operationmay be repeated until the fountain pen has been filled sufficiently.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a fountain pen, the combination with a barrel having an opening atone end, a closing member for said opening, a valve in said closingmember, a supporting pin for said valve, said supporting pin fittingtightlyv in said closing member at one end and loosely at the other, anda'cap for said barrel.

2. Ina fountain pen, the combination with a barrel having an opening atone end, a closing member for said opening, said clos ing member havinga screw-threaded connection with said barrel, a valve slidinglysupported in said closing member, a pin 1n said closing member adaptedto close said valve, said pin having a tight support at one end and aloose support at the other end, and a cap for said barrel. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
